Hi,
The following vulnerability was published for libslirp.
CVE-2021-3592[0]:
| An invalid pointer initialization issue was found in the SLiRP
| networking implementation of QEMU. The flaw exists in the
| bootp_input() function and could occur while processing a udp packet
| that is smaller than the size of the 'bootp_t' structure. A malicious
| guest could use this flaw to leak 10 bytes of uninitialized heap
| memory from the host. The highest threat from this vulnerability is to
| data confidentiality. This flaw affects libslirp versions prior to
| 4.6.0.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Regards,
Salvatore
